Connecting to the ports
External devices are connected to the SDI/DCH card by the following:
•
the NTAK19FB four-port SDI cable. This cable does not have to be
terminated at the cross connect terminal since it is equipped with
connectors.
•
the NE-A25-B cable. Terminate the NE-A25-B cable at the cross connect
terminal. Tables 225 through 228 give the pinouts for the SDI/DCH card.
